To lll t may concern 'Beit' known-"that I, CHARLES WQ citizen yoffftheUnited kStates of America, and a resident offthe cty'of St. Louis and State of Missouri, have invented certain nen7 and useful Improvements in a Valve Grinder, of which thefollovving is a speciiication. n '1' f `The primary object jof this invention vis to vprovide an improved device for holding and operating tools that areto be revolved.

Another object of the invention is to provide an improved operating tool holder in which thel actuating portionof the holder isv reciprocated for operating the tools in a revolving direction.

`Astill further object of'theinvention is to provide improved means in a tool operating device i'nf'v'vhich means are provided vsfliereby the stopping position of the'tool holdert'canbe chanded. j

.Y Another s tillj'furiller'object of the invention il's"t`o .l wrovide Alan'v` improved operating holder for tlie'revolubletool holding element of afvalvefgrinding'device. y t

Other and furtherv objects' `will appear yin the specification andV be specifically pointed out in the'appended claims, reference being had to the accompanying drawings exemplifyingthe inventi'om'an'd in which: y

"'With' 4'reference "to the accompanying drawings, 1 designates a guiding and holding' :element/Which is comprised of end me'mbers 2 and 3 and secured to said end members are guiding platesili and 5, said members beingspacedapartand arranged therebetween is a're'voluble member 6. lFormed in each of theflinembers' 1"and`5 i's a longitudinally extendingslot? and adapted to be "extended f' vertically through said slots which oppose one another' is a tool holding socket 8, said socket at its lower end also being engaged in the bore 9 which is arranged centrally in the revoluble member OGLE e,

When it is desired to change the stopping position of rotation oit' the valve which is created at the end of each stroke ot the meinber 1, the thumb ot' the gripping hand ot' the operator is borne downwardly on the engaging end 17 or' the stein 12 and lifting movement is applied to the hand gripping portion 1li and owing to the Jfact that thel socket 8 is secured to the gripping portion 14 by the pin 15, the socket 8 will be elevated in which the engaged pair or notches will be disengaged troni the cross pin 2T or the tooi 26. The member 1 is then moved so that the revoluble member (i will be revolved without being eiifective towards turning the tool 26, the revoiving oi: said member however, being ust enough to turn the soci-:e1 8 so that the cross pin 2?' will' be engaged by a different pair ot notches 25 ot said socket, when the gripping portion 15 is movedL downwardly such shifting position ot the socket relative to its engagement with the tool :26 providing for the stopping of the valve rotation being made at another point other than the previous stopping place, all olf which is for the purpose ot' preventing a quantity ot carbon from accumulating at a specific place between the valve and its seat.

For providing a take up to the cable 19 the lock nut Qillfwhen loosened on the draw bolt Q1 will permit the handle 23 when turned in a right hand direction to draw on said bolt and when the cable has been drawn tightly enough the nut 24 is then tightened against the end member 3.

For securing the revoluble member 6 to the socket 8 the head ot the screw 32 borne by said'uieinbcr is engaged in the recess 33 provided in the wall ot said socket.

lith the use ot a device ot this character for valve grinding, it is to be noted that a valve can be alternately revolved with rapidity and in which a valve can be ground on its seat in a very short space of time.

For preventing slipping ot the cable 19 in the groove 18 ot the member 6, said cable when being secured thereto is passed through an opening 34s formed in the member 6 before the w' idingl of the cable in the groove 1S is begun, then opposing portions of the cable are engaged in respective recesses 35 and are then wound in the groove 1S towards each other as shown in Figs. 2 and 3, and in which an intermediate portion 36 ot the cable is securely seated in the opening 841-.

iVhat I claim is:

l. In an operating tool holder, a reciprocable guiding member, a turnable element located in said member having its axis slid ingly supported thereby, said element adapted to support a tool, and means secured ad-- jacent each end ot said member co-operable with said element for turning said element in alternate directions when said member is reciprocated.

d. An operating tool holder comprised .of a turnable elementl bearing a tool receiving socket, a hand grip-ping portion for turnably supporting said socket, a reciprocal hold ing member for said element provided with a slot through which said socketl is mounted, and a cable secured at its ends to opposing portions ot' said member and wound around said element 'for revolving said element when said member is reciproeated.

An operating tool holder comprised of a turnable element bearing a tool receiving socket, a hand gripping portion for turnably supporting' said socket, a reciprocal holding member itor said element provided with a slot `through which said socket is mounted, a cable secured at its ends to opposing portions of said member and wound around said element for revolving said element when said member is reciprocated, and means provided tor adjusting said cable.

A revoluble member provided `with a `vinding groove on its periphery, a cable to be wound in said groove, said member having a seating opening or passageway ar? ranged parallel to the aXis thereof for the reception ot a portion of said cable.
